Discharge regulations volume

It is also necessary for this selection process to take into account the particular cooling system operational conditions (system volume, retention time, circulating water pH, etc.) and several other factors, such as discharge regulations, compatibility with other chemical treatments, and application costs. [Pg.213]

Control Devices In many installations the use of gas is intermittent, and some means of controlling the output of the compressor is therefore necessary. In other cases constant output is required despite variations in discharge pressure, and the control device must operate to maintain a constant compressor speed. Compressor capacity, speed, or pressure may be varied in accordance with requirements. The nature of the control device will depend on the function to be regulated. Regulation of pressure, volume, temperature, or some other factor determines the type of regulation required and the type of the compressor driver. [Pg.46]

For volume production of an aerosol fog of small particle size, on a large scale (suited to indoor use), the thermal aerosol fog generators appear to be very efficient. The Science Service experiments were mostly with this type. Two principal varieties have been developed. One discharges the insecticide solution or suspension as a relatively coarse spray into a jet of superheated steam delivered by a flash boiler of the tubular coil t3rpe. The other discharges that insecticide solution or suspension as a relatively coarse spray into a blast of hot gas emerging from a combustion chamber. The temperature is regulated by the controlled admixture of cold air. [Pg.61]

The Water Resources Act (WRA) 1991 provides for the regulating authority, the Environment Agency in England and Wales, to issue consents that include information on the composition of the discharge, volume, concentration and total amount of substances that can be released. Conditions vary on the use of the receiving watercourse but must ensure no deterioration in water quality. Registers of information are kept and are freely available to the public. The Water Industry Act... [Pg.265]

In 1996, for example, a Pollution Prevent (P2) plan was required if >1 Mg/month of hazardous waste was generated. P2 plans were also needed for storage volumes that exceed legally defined volumes if regulated substances were used in quantities exceeding the thresholds, and if toxic pollutant discharges required NPDES permits. [Pg.1327]
