Wastewater Treatment - Frequently Asked Questions

How much volume of wastewater does a Batch Treatment System treat?

Met-Chem can manufacture batch waste water treatment systems from 100 gallons per day up to our max of 10,000 gallons per day.

How much volume of wastewater does a Continuous Flow Wastewater Treatment System treat?

Met-Chem can design and manufacture chemical precipitation waste water treatment systems in flow rates from 5 gallons per minute up to 1,000 gallons per minute

How does a Batch Treatment System treat wastewater?
The batch will run its designed volume all at one time. Typical treatment plans include chemical precipitation via pH adjustment, solids settling via flocculant, and dewatering of solids with a filter press

How does a Continuous Flow Wastewater Treatment System treat wastewater?

The continuous flow will run at a rate lower than the max rating on the system. Typical treatment plans include chemical precipitation via pH adjustment into a two tank process, solids settling via flocculant in a lamella clarifier, solid thickening via a cone bottom tank, and dewatering of solids with a filter press

How much space does a Batch Treatment System require?

Due to batch treatment system handling lower volumes and the need for one treatment tank, the foot print is compact and great for any facility with space concerns.

How much space does a Continuous Flow Treatment require?

As the flow rates of our systems increase so does the overall footprint, However, Met-Chem will custom design a layout to work for your specific space needs.

What is the cost of a batch treatment system compared to a continuous flow system?

Due to handling a lower volume the batch wastewater treatment system is less expensive to purchase and install

What is the cost of a Continuous Flow Treatment System compared to a Batch Treatment System?

Due to the higher flow rates and multiple pieces of equipment a continuous flow wastewater treatment system will be more expensive to purchase and install.

Can a Batch Treatment System treat Cyanide and Chrome?

The system can be modified to add extra chemical treatment steps and chemical stations with metering pumps. Standard upgrades include bleach for cyanide destruct and meta bi sulfide for chrome conversion.

Can a Continuous Flow Treatment System treat Cyanide and Chrome?

The system can be modified to add extra treatment tanks, as well as extra metering pumps on the chemical feed skid. Standard upgrades include a two stage cyanide destruct system or a single stage chrome conversion.

Does a Batch Treatment System need a Lamella Clarifier?

The batch treatment system does not include a lamella clarifier, however due to running the system once per day, we can allow gravity and the chemistry the time to let it naturally settle and then process through the filter press.

Does a Continuous Flow Treatment System need a Lamella Clarifier?

A Met-Chem Lamella Clarifier is always included in our continuous flow systems. The Met-Chem Lamella clarifier uses a 50 minute retention/settling rate. This allows for a thicker solids slurry in the cone and clean water out of the clarifier discharge.

Does a Batch Treatment System need an Equalization Tank?

An equalization tank is used to hold the wastewater while the batch system is in use.

What is the purpose of an Equalization Tank in a Continuous Flow System?

An equalization tank is used to protect against short spikes in the flow rate
