Do not overinstall — layout is everything
Never install more units than the minimum
required for a particular wastewater treatment plant
There are instances of some air diffuser manufacturers drawing up plans that involve installing an excessively large number of units, perhaps because they have no confidence in their ability to calculate the actual number required. But with air diffusers, overinstallation is liable to lead to issues such as overaeration, because more air is injected to cover for the excess of units. Overaeration causes a state of overoxidation that can harm microorganisms and break up microbial flocs into so-called "pin flocs", which do not readily settle.
It also results in large outlays, including costs for construction, for piping, for the diffusers themselves, and for the continuous running of the diffusers.
OHR is committed to providing only the most optimized installation plans
Here at OHR, our guiding principle is that no good can come from overinstalling air diffusers. We always present plans with the fewest possible OHR AERATORs, in addition to clearly demonstrating our calculations and bases for doing so.
Please compare our required airflow rate, number of units for installation and the like with the same information from competing companies.
For air diffusers, layout is crucial
Unsuitable air diffuser layouts cause issues such as sludge accumulation without proper churning of the tank, or forcing the installation of extra air blowers when the DO rises less than expected.
It is frequently the case that diffusers are inappropriately arranged, even in plans drawn up by major wastewater treatment companies. That is to say, there are a great many sites where consideration has been given to the performance of the air diffusers themselves but the layout has been largely overlooked, resulting in poor wastewater treatment conditions.
Whether you will have to carry out diffuser replacement work time after time, whether you will continue being plagued by poor wastewater treatment and shelling out for chemicals to no avail — the decision as to which air diffuser to introduce is nothing more than the decision to leave all of this behind.
Backed by over 40 years of expertise and successes,
OHR always provides the optimal layout plans
Once apprised of the details of your wastewater (treatment volume, BOD/COD, etc) and the dimensions of your tank (length, width, water depth), we will draw up and provide you with bespoke arrangement and piping configuration plans based on the optimum number of the most suitable model of OHR AERATOR. This service is free of charge.
Conducting installation according to our plans provides a total guarantee that aeration can be performed without sludge accumulation or areas of stagnancy.
