bio-block Bio Block


A unique bacterial­-laden solid, combining a high bacterial count with slow release technology, to dose bacteria into wastewater and effluent handling facilities.

Chemtech Bio-­Block is a solid material that slowly dissolves, releasing bacteria for digestion of organic waste in higher flow systems such as lift stations, wet wells, etc. These beneficial bacteria are present in high numbers to handle difficult organic problems. This unique brick will gradually dissolve over a 30­90 day period which allows for continuous treatment and digestion of waste. The naturally­-occurring bacteria contained in the block will reduce odor, sludge, fats, oils, and grease buildup


  • Greatly reduces labor time
  • Reduces hydrogen sulfide
  • Cost effective/easy to use
  • No special equipment needed
  • Breaks down fat & grease buildup
  • Contains no chemicals
  • Enhances BOD/COD removal
  • Reduces sludge buildup
  • Changes biomass dynamics
  • Increases system efficiency
  • Eliminates malodors at their source
  • Degrades a wide range of complex organics


  • holding tanks
  • reactors and contractors
  • waste pumps
  • oxidation ditches
  • lift stations
  • activated sludge
  • lagoons

Chemtech’s Microbial Products are the industry-leading odor control, bioaugmentation, solids degradation, and corrosion prevention solutions. For over 20 years, we are the trusted and preferred supplier for a wide range of industries worldwide, including food processing, wastewater treatment, paper and pulp, refinery, and agriculture.

Safe, Natural Product

Microbe Lift O/C formula is a safe, natural product derived from organic matter consisting of natural soil constituents, including humate salts, humic acids, lignin matter and extractions of highly humified organic matters – powerful components that capture odorous compounds and interrupt their corrosive reactions, and enhance biological activities for solids degradation, reducing Total suspended solids (TSS) and Biochemical oxygen demand (BOD) levels. A township in Pennsylvania was able to keep their water safe by using Microbe Life

Effective, Environmentally Friendly, & Economical Solution

In industrial and municipal wastewater and sewage treatment plants, pumping stations, septic tanks, and grease traps, Chemtech’s Microbial Products are an effective, environmentally friendly, and economical solution used for the digestion of fats, oils, and grease, as well as the control and reduction of a wide range of odorous compounds, including hydrogen sulfide, mercaptans and ammonia, and their resulting corrosive effects.

What's in our product?

Chemtech’s Microbial products contain powerful bacteria and enzymes that act as organic catalysts to accelerate degradation of many organic polymers, including fats, proteins, plant carbohydrates, and certain types of solid materials.

Improves Efficiency

Microbe formulations effectively reduce treatment surcharges as well as frequency and severity of plant upsets, and remove specific waste compounds at higher rates. This ultimately improves the efficiency of treatment systems to produce higher quality effluents, helping to minimize operational costs and ensuring compliance with municipal and state regulations.

Safe for Personnel to handle

Chemtech’s Microbial products contain high numbers of naturally occurring bacteria that are effective for a wide range of degradation and treatment applications, and are safe for your facilities and personnel to handle.
