Mixing Technology for Municipal Applications

 

As populations grow in communities so does the need for the development and improvement of existing facilities across the globe. Federal guidelines continue to impact how effluent waters are treated to protect our ecosystems. Municipal treatment plants need to continue to search for new technology and processes that will meet nutrient removal guidelines, while balancing the practical need to reduce energy and operating costs. EnviroMix is committed to providing solutions that blend advanced technology with new or existing processes to effect positive change.

 

 

 

 


EQUALIZATION BASINS
Wastewater in equalization basins, if not thoroughly mixed, may stratify and leave settled solids when pumped back into the treatment stream.  BioMix systems provide homogeneity of effluent entering the treatment stream and reduce cleaning/maintenance requirements

 


AERATION

In municipal wastewater treatment plants, the aeration process accounts for 40% to 60% of total energy costs. BioMix enhances the efficiency of the aeration diffuser arrays by providing fast, effective mixing in areas of low oxygen demand.

 

 

SLUDGE DIGESTER

In aerobic digesters, the oxygen uptake rate of sludge entering the digester is extremely high for several days. Bottom-up mixing of the sludge with BioMix promotes effective oxygen transfer, facilitating digestion and preventing anaerobic conditions from occurring in parts of the digester.

 

BioMix may also be used for mixing in anaerobic digesters by using the biogas                                  of the digester instead of air as the mixing gas.


EFFLUENT CHANNEL

ChannelMix provides efficient mixing in effluent channels to promote a uniform distribution of suspended solids, minimize accumulation of surface scum, and reduce the formation of filamentous matter, thus improving flow through the entire length of the channel.

 


ANOXIC ZONES

BioMix provides complete mixing in anoxic zones with very low oxygen transfer using approximately half the horsepower of submersible mixers without the maintenance.

 

 

SLUDGE STORAGE

Thorough mixing in sludge holding tanks prevents settling and stratification, providing a homogeneous discharge for transport or disposal.

 

 

 

PUMP STATION

By maintaining solids in suspension and breaking up concentrations of fats, oils, and greases, BioMix promotes homogeneous feed to pumps. Benefits include less wear on pumps, reduced clean-out requirements, and more uniform pump station discharge, which enhances efficiency of subsequent treatment.
