OASES®

OASES® is an oxygen-activated sludge process for secondary treatment of wastewater. It is an automated, safe, and efficient oxygen-activated sludge treatment system for upgrading or retrofitting treatment facilities existing pure oxygen systems. 

Hydrex™ Chemical Solutions

Municipal Solutions

Hydrex™ is a range of water treatment chemicals proven to improve the performance and operating cost at treatment facilities. The chemical range includes both organic and inorganic chemicals formulated to meet the individual specifications of our customers in the municipal sectors.

Polymer Activation

Municipal Solutions

HydraPol™ Activ technology is an emulsion polymer activation system. Combined with Hydrex™ emulsion polymers it can be used optimize polymer usage for raw water, wastewater, process water and reclaimed water treatment, as well as for sludge dewatering.

OdoWatch® Odor Monitoring

Municipal Solutions

OdoWatch® continuously merges odor data with incoming weather data to display odor plumes on an on-screen map of the site and its surroundings. The system identifies main odor sources and can distinguish between site-generated odors and those originating from other sources.

ACTIFLO® Package Plants

Municipal Solutions

ACTIFLO® Package Plants is a complete range of pre-engineered and standardized ACTIFLO® units for the treatment of drinking water, process water as well as municipal wastewater and reuse.

BIOACTIFLO™

Municipal Solutions

BIOACTIFLO™ for Wet Weather Treatment can be used if flow diversion is not an option at a particular site, or the TSS and particulate BOD removal with ACTIFLO® alone are not enough. A biological solids contact tank can then be incorporated into the treatment flow path to improve soluble BOD removal through the system.

ACTIFLO® for Wastewater Treatment

Municipal Solutions

ACTIFLO® for Wastewater Treatment can be used at various stages of wastewater treatment including: enhanced primary treatment, wet weather clarification, high rate secondary clarification and final polishing for the removal of solids, phosphorus and metals.

ACTIFLO® CARB

Municipal Solutions

ACTIFLO® CARB process combines the benefits of microsand ballasted clarification with the adsorption capacities of PAC. With the addition of a PAC contact tank and a PAC recirculation loop, enhanced organic removal (up to 50% more than ACTIFLO clarification alone) can be achieved while maximizing the use of the PAC adsorption sites before being wasted.

ACTIFLO® for Drinking Water Treatment

Municipal Solutions

With over 260 surface water installations worldwide, the ACTIFLO® for Drinking Water Treatment can be found effectively treating low turbidity mountain runoff, reservoirs with algae, waters with high total organic carbon, hard water, soft water, ground water, flashy rivers and streams, brackish water and sea water.

Hydrotech Drumfilter

Municipal Solutions

Hydrotech Drumfilter provides an effective filtration system for fine solids removal and product recovery in lower flows or higher solids loading conditions. The drumfilter employs woven cloth filter elements installed on the periphery of the drum, and utilizes an inside-out flow pattern.
