NEW Wastewater Treatment

Team NEWater has the goal of developing an autonomous mixing and inject system to help aid the current N-E-W Tech(TM) BioChar Filtration System.

Design Task
The Injection system must be capable of autonomously and accurately inject a biochar iron mixture. The unit must also be scalable and can be monitored so that injection amounts can be altered.

Design Goals and Deliverables
1. Inject BioChar solution at rates from 0.25-10g/L of water and examine further scalability issues.

2. Meter rates of injection to within 10%.

3. Automated control of BioChar production and injection that can vary in solution to suit water under changing conditions.

4. System must be safe to operate and able to be mobile with existin container/vehicle combination.

SLIM (Solid Liquid Injection Manifold)
When large amounts of powders need to be added quickly into liquid or hard-to-disperse solids take too long to completely incorporate, an inline high shear mixer with sub-surface powder injection capabilities is extremely worth considering. The problem that lies here is that most injection manifolds are made for industrial sized scaled. We are currently look at smaller scaled version to work with the mobile unit and how we can make a working laboratory version.

This system works perfectly for our needs because:

1. The water enters the mixer and immediately encounters the biochar through a vacuum created by the rotor.

2. Product is injected directly into a high shear zone suspending the biochar into the water.

3. Resulting mixture is expelled centrifugally through the stator openings in a high velocity to the system.
