In the adsorption process, contaminants break their bond with the water molecules and chemically adhere to a filter media. This is typically accomplished by directing the water flow through pressure vessels containing the filter media at a rate that allows enough contact time for adsorption to occur. AdEdge Water Technologies’ Bayoxide E33 adsorption media is the industry standard for arsenic removal. This granular ferric oxide media reduces up to 99% total arsenic, including both Arsenic (III) and Arsenic (V).

Coagulation filtration is a process that introduces a coagulant, typically an iron or aluminum salt, to pretreat water contaminated with arsenic, iron, manganese, and/or sulfides. The process allows for significantly higher flow rates per square foot of media, creates less backwash water than other conventional treatment approaches, and has a smaller footprint which allows for lower operating and capital costs. This process involves a chemical addition, automated processes which decrease operator involvement and expense and does not generate a hazardous waste.

Filtration is a physical method of removing suspended solids from a solution. In water treatment applications, these solids may range from dirt, plant material, and debris washed into the water supply to bacteria, viruses, and other microscopic particles that occur naturally. These particles can damage pumps and valves, decrease the effectiveness of treatment processes such as disinfection, and cause the water to look dirty and undesirable for use.

Ion Exchange (IX) is a method of removing undesirable metallic salt ions from water by exchanging them with other ions attached to a media or resin. This chemical process occurs because ions have differing affinities for the resin and these ions will replace ions with less attraction as they flow over the media. The ions most often used as the exchange ions are sodium and chloride. Ions typically removed in this process are nitrate, uranium, radium, and other radionuclides. Eventually, the resin will be saturated with undesirable ions. Depending on the application, the resin may be regenerated on site, regenerated at a central regeneration facility, or be completely replaced and disposed of.

Reverse Osmosis (RO) membrane solutions from AdEdge Water Technologies use advanced membrane technology coupled with our other packaged treatment modules to create a complete integrated solution. Our systems can serve a variety of applications including drinking water, mining, boiler feeds, remediation, and industrial process water. Whether your water treatment application is for the reduction of total dissolved solids (TDS), total suspended solids (TSS), pathogens, or other contaminants, AdEdge can design a custom treatment solution to meet your needs.

Designed and built specifically for wellhead treatment, AD26 oxidation/filtration systems are engineered as stand alone systems for the removal of iron, manganese, hydrogen sulfide, and arsenic (if it coexists with high levels of iron). These systems are ideal for eliminating nuisance parameters and improving overall water quality.

With certain water parameters, an essential aspect of effective treatment is adequate pretreatment of the raw water before reaching the primary treatment system. This is true whether the application is for potable water, commercial, industrial, or environmental. Without proper understanding of the water chemistry and parameters that affect system performance, whether it is a media or membrane system, high operational costs or non-performance will result.

AdEdge – Rotec bring to the market an innovative desalination technology called Flow Reversal (FR-RO) designed to be implemented in existing and new desalination facilities for brackish water and other industrial applications, enabling significant system performance improvements, leading to higher profitability, reduced operating costs and environmental impact associated with desalination.

H2Zero Backwash/Recycle Systems conserve water by storing and treating contaminated backwash water from filtration and treatment systems. Nearly all water filtration related processes that remove target contaminants generate some liquid or solid residuals that need to be subsequently managed.

Groundwater is the primary water source for most communities in North America. With an increasing need to provide treatment for a growing list of contaminants, limited support staff, and shrinking operating budgets, water utilities face many hardships. Fortunately, biottta leverages nature to offer an affordable and sustainable solution for wellhead treatment of inorganic and organic contaminants.
