A liquid chemical product that treats liquidphase H2S; delivery of the chemical product; equipment to store and convey the chemical product; equipment to monitor H2S gas in specified locations; service to maintain the equipment; analysis of H2S monitoring data; and recommendations to SacSewer on process adjustments. SacSewer seeks a service contract with the most responsive and responsible Vendor to provide this comprehensive service. This service includes, but is not limited to data analysis, chemical product deliveries, remote chemical feed control, equipment and instrumentation installation, and postinstallation support (on-going equipment maintenance, monitoring/sampling/testing). SacSewer’s intent is to explore the best-available solutions, chemicals, and equipment. SacSewer seeks proven, universal, sustainable, and cost-effective solutions that can be applied throughout SacSewer’s existing wastewater collection system. Proposed solutions should be considered “turn-key” with minimal servicing required. Proprietary or “high maintenance” solutions are not preferred.
