Water & Wastewater Treatment

Q: How does AHT prevent water hammer in deep-well and booster pumps?

We program VFD S-curve deceleration curves coordinated with motorized check valves to eliminate pressure shockwaves.

Q: Are enclosures suitable for outdoor coastal water installations?

Yes, we fabricate IP66 double-wall panels with AISI 316L stainless steel and anti-condensation heaters for harsh coastal environments.

Q: Do you supply FAT documents and RTU integration protocols?

Yes, complete EPLAN schematics, Modbus/DNP3 mapping lists, FAT test sheets, and technical manuals accompany every shipment.

Utility Challenges & AHT Engineering Solutions

Water treatment demands 24/7 reliability where equipment degradation from moisture and chlorine is the primary cause of downtime.

Multi-Pump VFD & Soft Starter Panels

Challenge: High electrical consumption, water hammer shocks, and sudden pipeline rupture risks.

Solution: Multi-pump cascade drive panels with integrated PID pressure regulation, dV/dt motor filters, and automated soft ramp deceleration to eliminate water hammer.

Standard: IEC 61439-1 / CE
Energy Optimized

Corrosion-Proof MCCs (Form 3b/4b)

Challenge: High relative humidity, chlorine gas, and H2S causing terminal and busbar oxidation.

Solution: 316L Stainless Steel or C4/C5 marine epoxy coated enclosures, electro-tinned copper busbars, and conformal coated electronic circuit boards (ISA 71.04 G3).

Rating: IP55 / IP65
AISI 316L / C5 Coating

Wide-Area SCADA & Telemetry RTUs

Challenge: Distant booster stations and reservoirs with no fiber connections and unreliable power grids.

Solution: Solar-backed low-power RTU panels communicating via 4G/LTE, LoRaWAN, and DNP3/IEC 60870-5-104 protocols for centralized municipal SCADA management.

Water & Wastewater Engineering FAQs

Pump automation, corrosion defense, and remote monitoring standards.

How does AHT prevent water hammer in deep-well and booster pumps?

We configure specialized S-curve acceleration and deceleration profiles inside our VFDs and soft starters, synchronized with motorized check valve control logic programmed into the PLC to safely dissipate hydraulic transients.

Are enclosures suitable for outdoor coastal water installations?

Yes. For coastal desalination and wastewater facilities, we manufacture double-door IP66 enclosures using AISI 316L stainless steel with thermoset sunshades and condensation prevention heaters.

Do you supply FAT documents and RTU integration protocols?

Every control panel package comes with an As-Built EPLAN dossier, DNP3/Modbus tag addressing tables, instrument loop drawings, FAT protocol records, and full commissioning guidelines.
