Evobac STP Liquid Bacteria for STP

Aerobic Bacteria for STP Sewage Treatment Plant - Liquid

Sewage is inherently rich in organic matter, ammonia, fat, oil and grease. Most of the COD and BOD of sewage is due to organic compounds. The success of the sewage treatment process depends on the stability of the bacterial performance. Despite the best efforts of plant operators, STPs often experience fluctuations in operational conditions and the influent characteristics. Sometimes, inadvertently, STPs receive more than just sewage in the inlet stream. Generic bacteria often fail to maintain consistent growth with such fluctuations. As a result, the biomass is lost, and the system requires fresh bacterial dosing to recover the lost MLSS.

Evobac STP Liquid is a ready-to-use bacterial culture formulated for fast and convenient application. Its liquid form is ideal for automatic dosing pumps and regular maintenance programs, ensuring consistent bacterial activity with minimal operator effort. No mixing or activation is required, making it the preferred choice where ease of dosing and continuous treatment are priorities.

EVOBAC-STP is a stable microbial culture mix, tolerant to fluctuations in pH, variable COD, sudden drop in DO level, and toxicity. As a result, you get consistent performance over a long period without the need for re-dosing.

EVOBAC-STP

Bacteria in Evobac – STP multiply rapidly compared to inherently present bacteria in sewage. They break down complex polymers like proteins, fats, grease, carbohydrates, etc. into smaller monomers. Bacteria quickly consume these monomers as food. Evobac – STP helps reducing pathogens in the sewage. Bacteria in Evobac - STP work in both aerobic and anaerobic environments since it contains facultative bacteria along with aerobic bacteria.

Lower high COD rapidly

Reduces COD and BOD, Fat, Oil, Grease, and detergents.

Get Stable MLSS

Bacteria in Evobac-STP tolerate pH fluctuations (pH 5.0 to 9.0) and toxic shock loads. 

Get rid of bad smell

Eliminates bad odor,  foam and scum formation. No drop in performance even at low DO levels.

No Activation needed

No activation, overnight aeration is required. Simply add the ready-to-use bacteria directly in the aeration tank. No cow-dung or jaggery is required.

Safe Bacteria

These are GRAS bacteria as per FDA. Evobac-STP is completely safe to handle and use in open environment. 

Dosage Instructions

SOP for dosing, operational parameters, etc., will be provided along with technical support over the phone.

Evobac-STP vs Cowdung

2L of Evobac-STP easily replaces 1 ton of cow-dung.

Frequently asked questions

    How often do I have to dose bacteria in STP?
    The liquid bioculture needs to be added every 12 Months to once in 12 Months, depending on the effluent load and conditions. Liquid bioculture is best for regular maintenance dosing. Call us for exact dosing requirements. 

    How to add the product?
    It can be poured directly in the equalization tank or the aeration tank. A complete process will be given with the product.

    Does it need any activation, overnight incubation, etc.?
    No. The product is ready to use. Simply open the pack and add it to the system.

    Do we need to stop the STP while dosing the bacteria?
    No. Evobac-STP is added directly into an operating biological treatment system without interrupting normal plant operation.

    Is Evobac-STP safe to use?
    Evobac-STP is completely safe to use. It contains non-pathogenic bacteria and non-GMO microbes. These are GRAS status microbes, and the product is export-compliant. The product is exported to several countries, including European countries, and our product quality standards are the same globally.

    Is it compatible with other wastewater treatment chemicals?
    Yes. It is compatible with all the general wastewater treatment chemicals. There are a few precautions to be taken, which are explained in the SOP.

    Will it work in SBR, MBBR, or ASP?
    Yes. Evobac-STP can be used in all types of aerobic biological treatment systems, including SBR, MBBR, ASP, and similar STP processes.

    Does it help reduce ammonia and TN?
    Yes, Evobac significantly reduces Total Nitrogen in STP water. It has both Aerobic and facultative (anoxic) microbes. These bacteria form flocs that provide oxygenic (outer floc layer) and anoxic zones (inner floc layer) within the floc. This zoning inside flocs accelerates effective nitrogen removal.

    Can it reduce odors and foaming?
    Bacteria in Evobac-STP rapidly break down detergents, long polymers, and toxic compounds. They also lead to the complete digestion of aromatic organic compounds, leaving behind no volatile substances. As a result, they reduce foaming and bad odors within 2 days of application.
