Adhesives ETP COD BOD Reduction & MLVSS Growth

A 168 KLD Malaysian adhesives ETP achieved 90.66% COD and 93.99% BOD removal while increasing active MLVSS from 41% to 66% using BactaServe Aerobic & Anaerobic.

SV30 test showing MLSS settling and biomass development in the recycling kraft paper mill ETP aeration tank.

95% COD Removal in Recycling Kraft Paper Mill ETP

A 2,400 KLD recycling kraft paper mill ETP increased MLSS from 516 to 3,000 ppm in 30 days and achieved 95% COD removal using BactaServe Pulp & Paper at 42°C.

JCB loader loading wet municipal solid waste into a transportation truck before transit.

95% Odour Control During Municipal Waste Transport

A municipal waste facility in Goa achieved up to 95% odour control during wet waste transport using OdoServe SprayGel and OdoServe Odour Control, providing up to 2.5 hours of odour suppression and improving truck hygiene.

High-pressure misting system with SS header pipeline installed across the potato starch ETP for odour control.

Ammonia & H₂S Odour Control in Potato Starch ETP

A 300 KLD potato starch ETP controlled ammonia, hydrogen sulphide, mercaptans and volatile organic acid odours across three treatment zones using OdoServe with an optimised high-pressure misting system, improving odour control while reducing water, electricity and chemical consumption.

Fish processing ETP facility where NutriServe Rapid Oxidizer was used for condensate odour control.

90% Odour Reduction in Fish Processing ETP

A 600 MT/day fish processing plant achieved 90% condensate odour reduction using NutriServe Rapid Oxidizer. The treatment controlled obnoxious fish odours, reduced treatment costs by 30%, and added no additional load to the existing ETP.

Pharmaceutical ETP process flow diagram showing EGSBR, anoxic tanks, aeration tanks, MBR and RO treatment units for ammoniacal nitrogen removal.

98% Ammoniacal Nitrogen Removal in Pharma ETP

A pharmaceutical ETP reduced ammoniacal nitrogen (NH₄-N) from 708 ppm to 12.31 ppm using BactaServe Nutrient Removal. The solution achieved 98.3% reduction through biological nitrification and denitrification, improving nitrogen removal performance.

Hotel STP drainage channel with grease accumulation before biological fat, oil and grease treatment.

91% Fat, Oil & Grease Reduction in a Hotel STP

A 300 KLD hotel STP achieved 91.3% fat, oil & grease reduction using BactaServe™ FOG SR BAR. The solution eliminated grease scum, reduced COD by 81.3% and BOD by 88%, restoring healthy biological treatment performance.

MLSS Recovery & MBR Foaming Control in Automobile ETP

A 500 KLD automobile ETP achieved 60.7% filtered COD reduction, eliminated MBR foaming, reduced turbidity, and restored healthy brown biomass using BactaServe™ De-Bulking and a controlled sludge wasting programme.

Engineer inspecting a hazardous waste treatment site during industrial odour control assessment

90% Odour Reduction at a Hazardous Waste Site

A 100-tonne/day hazardous waste treatment facility reduced 24 hazardous gases by up to 99% and achieved over 90% odour reduction, significantly improving workplace safety and environmental compliance with OdoServe™.

Steel plant effluent treatment plant (ETP) treating coke oven wastewater with biological treatment units

99% Cyanide & Phenol Removal in Steel Plant ETP

A 3,600 KLD steel plant ETP achieved 99.5% cyanide removal, 99.2% phenol removal, and 94.3% thiocyanate removal using BactaServe™ Aerobic and BactaServe™ Nutrient Removal, protecting downstream MBR and RO systems while enabling reliable water recycling.

UASB digester port samples showing anaerobic sludge development in a pharmaceutical ETP

90% COD Reduction in a Pharmaceutical ETP

A 30 KLD pharmaceutical ETP achieved 88% COD reduction, lowering COD from 7,187 mg/L to 874 mg/L using BactaServe™ Anaerobic, while maintaining a stable VFA/Alkalinity ratio of 0.18 for reliable UASB performance and biogas production.
