Pre-treatment of wastewater

The purpose of wastewater pre-treatment is to remove contaminants such as solids, oils, greases, and chemicals before the wastewater enters the primary treatment process.

What is wastewater pre-treatment?

This initial stage focuses on removing large debris and solids from wastewater. Pre-treatment is a critical part of the entire treatment plan when dealing with wastewater. How effectively it is implemented will dramatically affect primary treatment and impact how much maintenance is required for pre-treatment equipment.

Pre-treatment is most effectively done above ground. The primary reason for this is maintenance. Underground systems or equipment, while out of sight, are far more difficult to maintain and require confined space entry. Since there have been so many past incidents of workers becoming disabled in confined spaces, there are strict guidelines related to entry and operation in any confined space and it is always better to avoid creating them.

the role of solids separation

Solid separation plays an important role in your wastewater treatment system. We offer many equipment specific to this part of the process. To get more information on all of ClearBlu’s solids settling solutions, contact us.

Settling Tanks

Settling tanks play an important role in the overall wastewater treatment process. Discover how you can manually or automatically separate solids from your water. A sedimentation tank allows suspended particles to settle out of water or wastewater as it flows slowly through the tank, thereby providing some degree of purification.

These settling tanks act as above-ground separators bringing the solids out through the bottom with automatic pinch valves into dumping hoppers. Oil and grease pass through the top of the tanks and don’t co-mingle with the settled solids.

Waterfall Screens

When you require the most effective method to remove solids, trust our ClearBlu wedge wire waterfall systems. View five reasons our products are the best.

ClearBlu manufactures wastewater screens as a highly efficient and cost-effective alternative to other solids removal systems. There are a number of factors that make our wedge wire screens an excellent choice.

Three Phase Separators

Three phase separators, (or clarifiers), are used for many applications requiring basic filtration before a waste stream can be discharged to a municipal sewer system. The basic concept is that wastewater enters the first chamber where the water is slowed and solids have an opportunity to settle out.

The chamber has a downturned pipe going to the second chamber. Since oil, grease, and some solids float, they get trapped in the first chamber. The concept behind multiple chambers is that the wastewater has an opportunity to clarify by passing through the chambers in sequence.

Aeration

Aeration

We believe the difference between good aeration and great aeration is in the size of the bubbles. Nanobubbles, which are not buoyant, are injected through the mixing system. These Nanobubbles provide an exponentially larger surface area per cubic foot of air than conventional fine or coarse bubbles by injecting over a billion bubbles per milliliter. The continuous flow creates a completely aerobic environment, as well as complete digestion.

The next stage is our unique, continuous flow Updraft Aerobic Digestion, utilizing Nanobubble technology. Wastewater is circulated through a dense media pack, with a volume multiplying mixing system. This is the ClearBlu Updraft Biodigester system. The bacteria are 60% more efficient because they have thousands of square feet of “fixed film” surface with this molded polypropylene honeycomb media.

FAQS

How can ClearBlu’s pre-treatment solutions help reduce costs in our facility?

Pre-treatment solutions can reduce maintenance and operational costs by effectively removing solids, fats, oils, and greases from wastewater before it enters the main treatment system. This pre-treatment reduces the load on downstream equipment, minimizing the frequency of cleaning and maintenance.

Additionally, efficient pre-treatment can prevent clogs and damage to equipment, extending its lifespan and lowering repair costs. By optimizing the wastewater treatment process, facilities can achieve more consistent and reliable operations, leading to cost savings.

What makes ClearBlu different than other pre-treatment companies?

We stand out in the pre-treatment wastewater industry through our focus on eco-friendly solutions, custom-designed systems, and expertise in handling diverse industrial needs. We emphasize the use of advanced technologies like aerobic digestion and oil-water separation, which can significantly reduce pollutants and maintenance requirements.

Lift Stations

The first stage in pre-treatment is lifting wastewater above ground. The best way to accomplish this is with circular lift stations. Circular lift stations are self-cleaning, so they do not require pump-outs, as do ground separators.

Waterfall Screens

The second stage of pre-treatment is screening. Removing solids is an important step prior to any further treatment and is a big money saver. Many times the screened material can be handled either as compost or animal feed.

Solids Settling

Once the wastewater is screened, solids settling is an option that can be effective if there is space and time. Many very fine and un-screenable solids will settle. An effective way to remove them is with cone bottom tanks. A cone bottom tank will concentrate sludge material into the bottom of the cone. It can then be removed to a storage tank, sent to a dewatering hopper, or sent to a filter press.

pH Balancing

The final stage of pre-treatment is pH balancing. Further anaerobic or aerobic treatment requires a pH range that is close to neutral. Removing solids in the previous steps will dramatically reduce chemical consumption since solids act as sponges. The type of mixing in a pH system will also affect how much chemical is consumed.
