Finding A Perfect Fit For Mix-And-Match Piping
Today’s water/wastewater piping options offer numerous advantages in terms of cost, performance, and anticipated service life. Unfortunately, utilities must still deal with what’s already in the ground — steel, cast iron, ductile iron, asbestos cement, plastic, concrete, and even wood. Here are guidelines on making transitions between old and new pipes of varying sizes and materials as smooth as possible.

Not All Sprockets Are The Same
There is a common misconception that all sprockets are the same, simply because they have the same number of teeth and run on 720-series chain. There are a number of other features that distinguish between a long-lasting, wear-resistant gear and a sprocket that needs to be replaced after a few years due to wear or failure.

LATEST INSIGHTS ON WASTEWATER
-
In areas with storm drains, the water can quickly overwhelm the drains, causing flooding hazards. For this reason, many towns have ordinances dictating how much ground can be covered with impermeable substrates.
-
Technology like advanced process control systems can streamline operations, create opportunities to lower costs and emissions, and ensure effluent quality meets the highest standards. Research also indicates that implementing an appropriate control strategy can help reduce N2O emissions.
-
Strategic flow monitoring helps wastewater utilities curb overflows, cut costs, and safeguard public health by turning accurate data into proactive action.
-
When seeking bids for a fair comparison, it’s important to evaluate the total cost of ownership.
-
Researchers have developed polyimide-based membranes for membrane distillation (MD) that overcome three persistent issues in membranes for water treatment and gas separations: the need for pore-forming chemicals that prevent recycling, performance degradation due to pore wetting and fouling, and the inherent trade-off between high water flux and selectivity.
