What Is A Bioscreen In The Septic Tank? (Question)

What is biobiowonder septic tank treatment?

  • BioWonder Septic Tank Treatment This septic tank treatment is suitable for drains, RV’s, toilets and other drainage systems. This product has been said to be made from natural products.

What is a bio tank?

A bio septic tank is a waterproof chamber where bacteria break down organic waste from wastewater without oxygen through anaerobic digestion. In biogas production, this chamber is also called a digester.

What is BIOSCreen in computer?

BIOSCREEN is a screening model that simulates remediation through natural attenuation of dissolved hydrocarbons at petroleum fuel release sites. The model is designed to simulate biodegradation by both aerobic and anaerobic reactions.

What does a bioCycle do?

A bioCycle™ Aerobic Wastewater Treatment System is a packaged sewage and water treatment plant for locations where mainline sewerage is not available. The system uses accelerated natural biological processes to purify all wastewater passing through it, which is then pumped out through garden irrigation.

How does a bio septic tank work?

The septic tank digests the solid organic matter and separates oils and grease (floatable matter) and larger solids from the sewage. The liquid (effluent) is then discharged into the ground from the septic tank via a soakaway system designed to slowly release the pre-treated sewage water into the soil.

How long does a BioCycle last?

The BioCycle wastewater treatment system is covered by full warranties: the electrical items for 24 months, up to 36 months if serviced by BioCycle, and the remainder of the system for 15 years.

How much power does a BioCycle use?

The Biocycle and similar SAF type systems use around 1.5kWhr/day.

What is a BioCycle septic tank?

The bioCycle™ system is a single tank system with four chambers designed to treat the wastewater to a very high Level. The final chamber in the pump chamber that pumps the treated waste water to the percolations area.

What are the signs that your septic tank is full?

Here are some of the most common warning signs that you have a full septic tank:

  • Your Drains Are Taking Forever.
  • Standing Water Over Your Septic Tank.
  • Bad Smells Coming From Your Yard.
  • You Hear Gurgling Water.
  • You Have A Sewage Backup.
  • How often should you empty your septic tank?

What are the disadvantages of a biodigester?


  • If organic waste and not only wastewater is fed into the digester, each day, the waste to be added needs to be mixed with water and/or ground to a liquid state.
  • Each day, the bio-digester effluent needs to be removed from the effluent tank.

What is the difference between a biodigester and septic tank?

A biodigester is a decomposition mechanized toilet system which decomposes human excretory waste in the digester tank using specific high graded bacteria further converting it into methane and water, discharged further to the desired surface. Septic Tanks yield sludge or septage which needs further de-watering.

BIOSCREEN, Natural Attenuation Decision Support System

BIOSCREEN is a screening model that mimics cleanup at petroleum fuel discharge sites by simulating natural attenuation of dissolved hydrocarbons in the environment. The model is intended to replicate biodegradation including both aerobic and anaerobic events in a laboratory setting. Ground water remediation managers will be able to use this screening technique to identify places where natural attenuation is most likely to be beneficial to human health and the environment, and to prioritize those sites for further investigation.

With the help of this software, which was developed in the Microsoft Excel spreadsheet environment and based on the Domenico analytical solute transport model, you will be able to simulate advection, diffusion, adsorption as well as aerobic and anaerobic reactions, which have been shown to be the dominant biodegradation processes at many petroleum release sites.

  • Solute transport without decay
  • Solute transport with biodegradation represented as a first-order decay process (simple, lumped-parameter method)
  • Solute transport with biodegradation modeled as a first-order decay process (complex, lumped-parameter approach)
  • In this model, dissolved oxygen, nitrate, and sulfate serve as soluble electron acceptors for the biodegradation process, which occurs in an instantaneous time frame.

Septic Systems

Private Septic SystemsIn Woodbury County, the Siouxland Distict Health Department holds the primary responsibility for regulation of private septic systems serving 4 homes or fewer or less than 15 people. Siouxland Distict Health oversees any individuals, homeowners, or contractors installing systems to ensure compliance with the minimum state standards developed by the DNR.Chapter 69: Onsite Wastewater Treatment and DisposalThe DNR standards specify siting and construction requirements relative to the primary and secondary treatment portions of the sewage disposal systems as well as minimum depth to groundwater, minimum separation distances to potable water sources, and maximum percolation rates for soils. The DNR standards are primarily a prescriptive code giving design criteria for each alternative type of secondary treatment system permitted. The Siouxland District Health Department does have the authority to allow alternative or innovative performance based systems.Installation of Private Septic SystemsPermittingAny individual, homeowner or contractor seeking to install a private sewage system is required to obtain a permit to construct systems in Woodbury County. Currently, septic systems require both a pre-construction site inspection and post-construction inspection prior to back filing to verify compliance with code requirements.Click hereto obtain an application for a Private Septic System for Woodbury County.Time of Transfer InspectionsIowa’s time of transfer inspection law went into effect July 1, 2009.

Septic System Information and Care

When municipal sewer service is not available, a septic system that has been properly constructed and maintained is an excellent option for treating wastewater and protecting groundwater quality. Septic systems are comprised of two major components: the septic tank and the drainfield.Waste from toilets, sinks, washing machines, and showers is channeled into the septic tank, which is a holding tank typically constructed of pre-cast concrete or fiberglass and is sized according to the estimated wastewater flow from a given-sized residence or business.The septic tank separates the wastewater into three general components: solids or “sludge,” floatables or the “scum In the first stage of wastewater treatment, anaerobic bacteria (bacteria that can survive in an oxygen-free environment) break down solids into liquids and generate gas that is vented through the building’s plumbing vent stack.

The second stage of wastewater treatment is performed by aerobic bacteria.

Because it allows aerobic (oxygen-using) bacteria to continue deactivating the disease germs that remain in the wastewater, the drainfield serves as a secondary treatment facility for sewage.

Additionally, evaporation of water occurs through the layer of soil covering the drainfield.In some areas where soil types such as clay layers or bedrock exist, or in areas where there is a shallow seasonal high water table, septic systems must be elevated above the ground surface.Septic systems must be elevated above the ground surface in areas where there is a shallow seasonal high water table (“mounded” systems).

Other areas, such as flood zones near rivers or other bodies of water, traditional septic systems may not be sufficient to treat the wastewater.

In certain instances, modern wastewater treatment systems that “aerate,” or add oxygen to the wastewater, may be necessary to treat the effluent.

Others are equipped with chlorinating chambers or peat moss-based filtering chambers, which kill disease germs before they may infiltrate into groundwater supplies.

Septic System Care

Don’t flush cigarette butts, tampons, condoms, or any other indigestible things down the toilet or down the sink drain. Consequently, the exit filter or drainfield will become clogged. Never throw grease down the drain since grease cannot be digested by the septic system and will cause it to become clogged! rather than dumping it in the garbage, pour it into an empty container or bottle and throw it away. Make sure you don’t use excessive amounts of bleach or other cleaning agents in your septic tank since doing so will interfere with the bacterial operation inside the tank.

  1. Instead of doing numerous loads of laundry back-to-back, stretch your wash loads out over the course of the week to reduce the amount of water that the septic system has to treat (a normal wash load consumes between 60 and 90 gallons each load!).
  2. Roots from trees and plants will grow into the drainlines and cause them to get obstructed.
  3. Driving over your drainfield can cause the pipes to become crushed or the dirt surrounding them to become compacted, and driving over your septic tank can cause the lid to fracture or even fall apart!
  4. Consider the installation of water-saving showerheads, toilets, and other water-saving appliances in your home.
  5. Septic tanks should be pumped out every four to five years, according to the Florida Department of Health, in order to prevent the buildup of sludge in the tank over time.
  6. Stoppages and overcrowded drainfields are caused by leaking toilet flapper valves, which can allow hundreds of thousands of gallons of waste water to enter your septic system each day.

Additional Resources for What is a Septic System?

According to the Massachusetts Department of Environmental Protection, a properly maintained septic system should be pumped out at least once every three years! Regular maintenance is the most crucial factor in ensuring that your septic system is in good working order. Pumping on a regular basis helps to keep particles from leaking into the drainfield and blocking the soil pores. While the frequency of pumping depends on the amount of consumption, the Massachusetts Department of Environmental Protection advises that systems be pumped at least once every three years for households without a trash disposal.

  1. The frequency with which you pump should be determined by the amount of water that has accumulated and the amount of water that has been pumped in the past.
  2. It is astounding how many system owners assume that if they have not experienced any difficulties with their systems, they do not need to pump out their tanks.
  3. Solid materials sink to the bottom of the tank when your system is utilized, resulting in the formation of a sludge layer.
  4. In most cases, correctly engineered tanks have adequate room to safely store sludge for up to three to five years at a time.
  5. As the amount of sludge in the system rises, more solid wastes are allowed to escape into the soil absorption system (SAS).

When hiring a pumper, be certain that they are licensed by the local Board of Health, and always insist on receiving a paid receipt from the pumper that clearly outlines the terms of the transaction and the amount you paid (how many gallons were pumped out of the tank, the date, the charges, and any other pertinent results).

In addition, a copy of this report is forwarded to the local Board of Health by the pumper.

Additional Resources for How often should I pump out my septic system?

  • Once every 3 to 5 years, have the system examined and pumped out. If the tank becomes overburdened with sediments, the wastewater will not have enough time to settle before it overflows down the drain. After that, the extra solids will be carried to the leach field, where they will block the drain pipes and the soil. Always know where your septic system and drain field are in relation to your house and keep a detailed record of all inspections, pumpings, repairs, contract or engineering work for future reference. Keep a sketch of it on hand for when you go to the service center. The drain field should be planted above the septic system with grass or small plants (not trees or bushes) to help keep the system in place. Controlling runoff through imaginative landscaping may be an effective method of reducing water consumption. Install water-saving devices in faucets, showerheads, and toilets to limit the amount of water that drains into the septic system and into the environment. Replace any dripping faucets or leaking toilets, and only use washing machines and dishwashers when they are completely full. Avoid taking long showers. Roof drains as well as surface water from roads and slopes should be diverted away from the septic system. Maintain a safe distance between the system and sump pumps and home footing drains as well. Take any remaining hazardous substances to a hazardous waste collection station that has been approved by the local government. Use bleach, disinfectants, drain and toilet bowl cleaners sparingly and in line with the directions on the product labels. Only utilize septic system additives that have been approved for use in Massachusetts by the Massachusetts Department of Environmental Protection (MassDEP). In Massachusetts, it has been found that the additives approved for use have no detrimental effect on the particular system or its components, or on the environment in general.
  • Non-biodegradables (cigarette butts, diapers, feminine items, and so on) and grease should not be disposed of down the toilet or sink. The use of non-biodegradable materials can clog the pipes, and grease can thicken and block the pipes as well. Cooking oils, fats, and grease should be stored in a container and disposed of in the garbage
  • Paint thinner, polyurethane, antifreeze, insecticides, certain dyes, disinfectants, water softeners, and other harsh chemicals should all be added to the system to ensure that it works properly. Septic tank malfunctions can be caused by the death of the biological component of your septic system and the contamination of groundwater. Typical household cleaners, drain cleaners, and detergents, for example, will be diluted in the tank and should not cause any damage to the system
  • And Make use of a garbage grinder or disposal that drains into the septic tank to eliminate waste. If you do have one in your home, you should use it only in extremely limited circumstances. The addition of food wastes or other solids lowers the capacity of your system and increases the frequency with which you must pump your septic tank. If you utilize a grinder, you will have to pump the system more frequently. Trees should be planted within 30 feet of your system, and vehicles should not be parked or driven over any section of the system Tree roots may block your pipes, and heavy cars may cause your drainfield to collapse
  • However, you can prevent this from happening. You should not allow anybody to work on your system or pump it without first ensuring that they are licensed system specialists
  • Wash an excessive number of loads of clothing in your washing machine. Doing load after load deprives your septic tank of the time it needs to properly process wastes and causes the entire system to become overwhelmed with surplus wastewater. As a result, you might be overflowing your drain field without giving yourself enough time to recover from the inundation. To calculate the gallon capacity and the number of loads per day that may be safely pumped into the system, you should speak with a tank specialist. Cleaning the plumbing or septic system using chemical solvents is recommended. Microorganisms that devour toxic wastes will be killed by “miracle” chemicals that have been developed. These items have the potential to pollute groundwater as well.

Key Actions for Septic System Do’s and Don’ts

Septic systems that have been properly maintained can assist in preventing the spread of disease and other illnesses. System failures can have serious consequences.

  • Your failure to maintain your water system could pose a serious health hazard to your family and neighbors, degrade the environment, particularly lakes, streams and groundwater, reduce the value of your property while also being extremely expensive to repair
  • And put thousands of water supply users at risk if you live in a public water supply watershed and fail to maintain your system.

Keep an eye out for the following warning signals of a malfunctioning system:

  • Surface sewage over the drainfield (particularly after storms)
  • Sewage backups in the home
  • Lush, green vegetation over the drainfield sewage smells
  • Toilets or drains that are difficult to empty

If your system fails, the first thing you should do is call your local board of health, which must authorize all modifications and the majority of repairs before they can be carried out or installed. The board of health will inform you of the steps that must be taken. In the event that your system fails, call your local Board of Health immediately!
