Biodegradable Water Optimizer

Meeting today’s restrictive discharge requirements is an issue for all wastewater treatment facilities. As a result, municipalities and industrial wastewater treatment plant (WWTP) operators and owners are facing more restrictive regulations and potential litigation from local and federal agencies. In response to the issues surrounding WWTP’s compliance, Apex Engineering Products Corporation has developed RYDALL WO.

RYDALL WO is a Water Optimizer that is an environmentally safe additive which results in the reduction of hydrogen sulfide (H2S), chemical oxygen demand (COD), biochemical oxygen demand (BOD), fats, oil, and grease (FOG), total dissolved solids (TDS), and total suspended solids

(TSS). This unique biocatalyst also effectively enhances methane (CH4) production and dissolved oxygen (O2) content.


  • Biodegradable
  • Contains no bacteria
  • Non-toxic to humans, animals, fish & plants
  • Safe, even at high concentrations
  • No health risk to personnel handling the product
  • No fumes or irritating vapors
  • Non-flammable
  • Non-corrosive to metals, concrete and plastics

RYDALL WO is a highly concentrated, complex mixture of nutrients, vitamins and trace elements. The solution contains no bacteria, is biologically degradable and non-toxic for humans, animals, fish and plants. RYDALL WO is safe, even at high concentrations and poses no health risk to personnel handling the product. No fumes or irritating vapors are released from this product which is non-flammable and non-corrosive to metals, concrete and plastics.


WWTP’S — RYDALLWO can be metered into the sewer lines feeding the WWTP’s or can be added into the WWTP directly. The amount of RYDALL WO that is required depends on the retention time and the aerobic or anaerobic condition of the system.

LAGOONS — RYDALL WO can be introduced and mixed into the lagoon to control odours and enhance dissolved oxygen levels. The increased dissolved oxygen levels and the constituents of RYDALL WO promote lower COD and TSS levels within the lagoon.

SLUDGE HANDLING FACILITIES — RYDALL WO can be sprayed on sludge from the sludge dewatering equipment or metered into the sludge holding tanks. This can result in significantly reduced levels of atmospheric hydrogen sulphide in these facilities. H2S reduction rates of 95% are observed in most cases.

SEWERS — RYDALL WO can be used to prevent corrosion which commonly occurs in sewer lines. Metering RYDALL WO into these lines allows for the stabilization of the wastewater, which in turn disallows the formation of hydrogen sulfide.

OTHER APPLICATIONS — Applications for RYDALL WO are practically limitless, including food processing plants, slaughterhouses and animal by-products, pulp and paper plants and any application that needs wastewater treatment, corrosion control, odor control or methane enhancement.
