A new technology, hydrodynamic cavitation (HC) is used to ,deal, with this ,wastewater, produced in fish processing plants. The orifice plate is used in the HC reactor to generate a cavitation effect. The intensification of this technique was carried out with the help of hydrogen peroxide (H 2 O 2 ) and TiO 2 .

Dissolved-oxygen meters can be used to monitor oxygen drops ,in wastewater, systems, indicating that more air is necessary to maintain treatment or that a suddenly increasing dissolved oxygen level may be due to biomass die-off. Sudden drops in alkalinity can be an indicator of an ,acidic, slug of chemicals coming into the system.

Nickel can also end up in surface water when it is a part of ,wastewater, streams. The larger part of all Ni compounds that are released to the environment will adsorb to sediment or soil particles and become immobile as a result. In ,acidic, soils, however, Ni becomes more mobile and often leaches down to the adjacent groundwater.

Some septic system owners decide to take the DIY drainfield approach when they encounter a problem with their system. Usually, this entails draining the ,wastewater, and then digging a bed of rocks as a way of repairing the failed drain field. This or any other form of DIY drainfield repair and replacement is not only dangerous but also illegal.
