Guardian Environmental Products Inc. products

Guardian applies our experiences in application, engineering, and sales of chain and scraper clarifiers, to bring a truly integrated and customized solution to each of our customers’ wastewater treatment system needs. Our staff provides one-on-one customer consultation to ensure proper equipment is matched and provided, aiming to exceed each customer’s expectations.

Dissolved Air Floatation (DAF) systems are used for enhanced floatation or thickening. The DAF separator uses microscopic air to enhance the floatation of particles that would settle or rise slowly through gravity separation to enable smaller tankage.  The Dissolved Air Floatation Thickener uses similar microscopic air technology to thicken high solids waste such as Waste Activated Sludge (WAS) and thickens the material prior to digestion or dewatering. This greatly reduces the digester volume or overall capacity.

Rectangular API collectors are used for separation of wastewater flowage using floatable petroleum products which float, and heavier sludges that sink.  These systems require the experience of Guardian Environmental Products wastewater engineers in proper design configurations and material selections to ensure a reliable system.  Most refinery API collectors are covered with either floating covers or structural covers with nitrogen gas blankets.   Each adds a complexity and need for equipment reliability significantly different that typical municipal applications.

Guardian Environmental Products design and control options are customized for every application and every user.  Our systems range from local start/stop controls to sophisticated PLC controls that are able to monitor and control all aspects of the collector system as well as the overall performance of the complete clarifier system all through a touch screen display. Our process experience combined with our rectangular clarifier design experience are unmatched in the industry.  Our CFP (Collector Failure Protection) system and BOSS (Biological Optimized Sludge System) are exclusive designs that can be integrated to the plant SCADA system for the ultimate control and optimization.

Scum pipes are used to collect and discharge floated material to nearby scum for removal or digestion.  We provide a variety of designs to fit every customer’s needs and system requirements.  Material options include steel, stainless steel, and fiberglass.  Systems can range from manually actuated lever control to rotate the scum pipe and withdraw float to handwheel actuated to automatically actuated with an electric actuator.  Our shop fabrication can often provide the maximum corrosion protection, through the use of our stainless-steel design that is not affected by UV light or environmental erosion for the same cost as other supplier’s fiberglass or carbon steel designs.

Weirs and troughs: Guardian designs trough and weir configurations for proper end even flow distribution.  Or troughs can be either stainless steel or fiberglass and include leveling and adjustable v-notch or flat weirs.
