Gravity feed water treatment system

A gravity fed water treatment system comprising:

• a flocculation system including a flocculation system inlet for receiving water and a flocculation system outlet for dispensing flocculant-treated water, the flocculation system including a flocculation tank for use with a flocculant agent for encouraging coagulation and settling of particles suspended in the water in the flocculation tank;
• a foam filter system having a foam filter system inlet for receiving water, the foam filter system including a foam filter element for filtering microbes and particles out of the water and capable of facilitating growth of biological organisms for treating the water;
• a restriction orifice for restricting water through the foam filter element to control a flow rate and face velocity of the water;
• and
• a water treatment system outlet for dispensing treated water that has passed through the flocculation system and the foam filter system.

A gravity fed water treatment system comprising:

• a first container having a first container inlet for receiving untreated water and a first container outlet for dispensing flocculant-treated water, the first container for use with a flocculant agent for encouraging coagulation and settling of particles suspended in the water, the first container including a manually operable valve capable of selectively dispensing flocculant-treated water from the first container via the first container outlet;
• and
• a second container having a second container inlet for receiving the flocculant-treated water, a second container outlet for dispensing disinfected water, and dual radial foam filters for filtering microbes and particles out of the water, each radial foam filter capable of facilitating growth of biological organisms for treating the water, the dual radial foam filters plumbed in parallel by a conduit fitting having two inlets and a single outlet in communication with the second container outlet;
• a restriction orifice for restricting water through the dual radial foam filters to control a flow rate and face velocity of the water;
• and
• wherein the first and second containers are nestable and stackable.

A method for treating water using a gravity fed water treatment system, the method comprising:

• passing water into a first container through an inlet;
• adding flocculant to the first container to encourage coagulation and settling of particles suspended in the water;
• waiting a predetermined period of time until the particles coagulate and settle to the bottom of the first container;
• manually opening a first valve to pass flocculant-treated water from the first container into an inlet of a second container under the force of gravity;
• passing the flocculant-treated water through dual radial foam filters under the force of gravity to filter microbes and particles out of the water, the radial foam filters capable of facilitating growth of biological organisms for treating the water;
• manually opening a second valve disposed on an outlet of the second container to dispense disinfected water from the water treatment system under the force of gravity;
• and
• metering the face velocity of water flow through the dual radial foam filters with a restriction orifice located downstream of the radial foam filters to provide effective filtration of the water.
