At last, a totally "Green" sustainable wastewater treatment system that's cleaner than HRSD.The BaySaver™ series of wastewater treatment systems are designed around an Aerobic Treatment Unit and a subsurface drip dispersal network. The process units are housed in a single concrete tank for structural integrity. All treatment units of this type work by using the bacteria that nature has provided. By pumping air into the system, the bacteria grow and thrive in much larger amounts than would occur naturally. The over population of bacteria speeds up the process of breaking down domestic wastewater, making it safe for release into the environment. The result of this process is a clear, odorless effluent, which meets or exceeds state water quality standards. Wastewater is then applied to the dispersal field using low pressure drip tubing, in short doses several times per day near the soil surface, directly in the plant root zone where the soil dries the quickest. This soil horizon is the most biologically active and will increase the nutrient removal of the wastewater via bacterial breakdown and plant uptake. Aerobically treated effluent with drip dispersal results in about a 90% reduction in Nitrogen to the water table as compared to conventional Septic. Some major advantages of engineered drip dispersal:
BAYSAVER DRIP™ Drip Dispersal PROCESS DESCRIPTION Wastewater enters a pretreatment/settling tank similar to conventional septic tanks. In this tank, debris and settleable solids settle to the bottom and are decomposed by anaerobic bacteria. The effluent enters the Activated Sludge Wastewater Treatment System from the primary tank where it is introduced into an oxygen rich environment. In this oxygen rich environment, a colony of bacteria, called the biomass, develops and is capable of digesting (breaking down) biodegradable waste into carbon dioxide and water. This is a continuous process as long as the biomass is supplied with incoming wastewater and oxygen. There are no moving mechanical parts or filters in the ATU. In this system, conditions are favorable to heterotrophic bacteria which consume many times their weight in waste per day. In addition to CBOD and TSS reduction, ammonia nitrogen is converted to nitrates, a form of nitrogen that plants can readily use. Wastewater nitrification of the ammonia and denitrification of nitrates occur within the bacteria masses. A 70%+ removal rate of total nitrogen is common without any type of recirculation or cycling of the blower. The result of this process is a clear, odorless discharge, which meets or exceeds state water quality standards. This high quality effluent is similar in strength to storm water and therefore can use a smaller disposal area. Typically the required square footage is the same as an Ecoflow or Advantex system. Subsurface drip is a highly efficient method to dispose of effluent. Small, precise amounts of water are uniformly applied under the soil surface from multiple points.
